Vodacom refusing go refund me.

It simply feels like vodacom is refusing to refund me my money that they debited me twice. This happened at the beginning, the month is almost over yet I have received nothing, whenever I send a email there response is "the refund is being processed". Last person that emailed me back was Tshepiso, BackOffice Support. Which was the 17th April, it's the 23rd and still nothing....your services are really pathetic.
